SAFETY-VALVE ATTACHMENT FOR LAMPS.

EPLGIFICATION forming part of Letters Patent No. 341,483, dated May 11,1886. Applicaiion filed January 8, 1885. Serial No. 152,256. (No model.)

T 60% whom, it may concern:

Be it known that I, EZRA WILLIAM INGLE, a citizen of the United States,residing at Fort \Vorth, county of Tarrant, and State of Texas,

have invented certain new and useful Improvemenis in Safety-ValveAttachments for Lamps; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, in which Figure 1 is a side view of alamp-top and burner with my improved safety-valve applied thereto; Fig.2, a sectional view of the lamptop with the burner removed; Fig. 3,aplan 5 view of the hinged collar; and Fig. 4 a detail view inperspective of the valve.

The present invention has relation to safetyvalve attachments for lamps,to permit of the escape of any gas which may be formed in the upper partof the oil-reservoir by the eva porization of its contents; and theobject thereof is to provide a simple form of valve stamped from asingle piece of sheet metal, with a shank adapted to be inserted througha slot in 5 the lamp-collar and the valve afterward bent down over thevalve-opening, thus presenting a valve that will be sensitive to thepressure of gas within the reservoir, and consequently insure itssuccessful operation at all times, while the valve is capable of beingproduced at comparatively small cost and attached to the lamp withlittle trouble, as will be hereinafter described and claimed.

In the accompanying drawings, A represents 5 the usual lamptop providedwith a screwthreaded neck for attaching it to thelampreservoir, and Brepresents the collar hinged to the top A, and held down thereonbyasuitable fastening, a. I

The collar B has interior screw-threads for connecting thereto the usualburner, C, and is formed with a valve-opening, d, and immediately aboveit a slot, 0, these collars, as above described, being stamped fromsheet metal, either ornamental or plain. It is the object to manufacturethese collars complete, ready to attach to the top of any lamp, afterwhich any one can apply the valve, it being simply stamped from sheetmetal by suitable dies, the valve, as shown at D, having a shank, b.

In applying the valve to the collar B, all that is necessary is toinsert the sheet-metal shank 1) down through the slot 0 and afterwardbend the valve D down against the surface of the collar until it fitsnicely over and around the valve-opening (I, thus enabling it to bequickly and conveniently attached by most any one, as no hinging thereofto the collar is required or any means of attachment that would requirea skilled workman.

The valves, being cut or stamped from sheet metalcomplete and ready forattachment to the lamp, can be made in large numbers and placed in themarket for the trade at a comparatively small cost, and can be appliedby any one.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

The combination, with a lamp-collarhaving a valve-opening therein and aslot immediately above it, of a hingeless valve formed from a singlepiece of sheet metal,with a shank entering the slot, and the valve bentdown over the opening, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

EZRA \VILLIAM INGLE.
